Chuck VanVolkingburgh and Stephen Cunningham have both been programming and working with CNC machinery for more than twenty-five years each (50 years combined experience). As reseller employees, they have helped to train thousands of GibbsCAM users from hundreds of large and small machine shops over the past eighteen years. Companies like Precision Drilling, National Oilwell Varco, Weatherford, Redline-Pro, Drilformance, Promac and hundreds more have taken our classroom and on-site training. Over the years we have developed a well organized curriculum which produces capable GibbsCAM users.
